26 HYDRAULICS & PNEUMATICS November/December 2021 www.hpmag.co.uk S.S. White Technologies, provider of flexible rotary shafts for the aerospace industry, supplied flexible shafts that transmit power to activate the critical Collins Aerospace Thrust Reverser Actuation Systems (TRAS) on the Pratt & Whitney (IAE) V2500 turbofan engines that just passed 250 million flight hours of service. S.S. White provided a set of hydraulically activated flexible rotary shafts per IAE V2500 that transfer power and enable safe operation of the Collins Aerospace TRAS during flight and deployment of the TRAS during landing. Maximum bending flexibility and torsion strength In addition, all aerospace flexible shaft products are designed to one of the industry’s highest performance criteria by utilising Perflexion, a computer modelling software program developed by S.S. White. This program allows the design engineers more fully to model the behavioural characteristics of the wire bundles within the shaft core and arrive at an optimum product that provides maximum bending flexibility and torsion strength while allowing minimal torsion deflection with up to a 30% improvement above current industry standards. S.S. White Technologies is a designer, engineer, manufacturer and tester of a wide variety of flexible shaft products for the aerospace, medical, automotive and industrial markets around the globe. S.S. White Technologies comments that almost all of the commercial and military aircraft platforms in the air today (except Russian), and more than half of US-manufactured cars rely on its flexible shaft products. The company currently has manufacturing facilities in the US, the UK and India. www.prattwhitney.com S.S. White rotary shafts activate actuation systems on Pratt & Whitney V2500 turbofan engines In 2020, Hydroscand Machine AB launched a range of lightweight crimping machines. The company reports that these have proved to be extremely popular due to the genuine portability of the H16LW handheld machine and the significantly reduced weight of the H24LW, meaning service vehicles fitted with this machine can carry 50kg additional stock. Following on from the success of the lightweight machines and in line with customer demand, Hydroscand Machine has developed the H60D AutoCal 4” Crimper. The H60D is designed to be used for the toughest applications and has a crimping range of up to 128 mm, 350-ton crimping force and can crimp hoses up to 4” diameter. Increased flexibility According to Hydroscand Machine, it is an ideal machine for a workshop, hose branch or hose assembly production facility. The company adds that, with this machine, users can press the toughest hydraulic hoses and industrial hoses up to 4”. The H60 machine provides increased flexibility in terms of the range it can provide. It is available as the H60D BASIC model or as H60D AUTOCAL. The latter is equipped with a user-friendly digital control for faster entry of crimping data. The automatic calibration system warns you at pre- set intervals that calibration is needed, and calibration can be completed in just ten seconds. Hydroscand Machine manufactures a wide range of assembly machines and accessories for the hydraulic hose industry. Hydroscand Group comments that its 50 plus years of experience in the hose assembly business has given it a unique understanding of the needs of machine operators, which informs the production and development of Hydroscand Machine’s large machine range. Environmentally friendly Hydroscand Group adds that its machines are built to be as environmentally friendly as possible, easy to use, ergonomic and to meet high international safety standards corresponding to European CE- regulations. www.hydroscand.co.uk HYDRAULICS Hydroscand launches new H60D swager TRAS open 747 Nacelle.
